Sorry for confusion. Your interpretation was completely right though.

What I'm aiming for is something like Paul Sawyer's regular column in White Dwarf magazine some years ago: He built up a Chaos force by a set amount of money, so one could follow his monthly purchases. I tried to copy that for some of my historical projects which I started in public, to help people estimating the actual cost for similar ideas.
Besides, thanks for the link. Now I've to order some dinos.

EDIT: Where did you get these Tamiya Velociraptors? Couldn't find them on the web yet.
